Abstract
An apparatus and method for producing copies of documents successively fed into a copier/duplicator in a chain feeding mode of operation. The copier/duplicator operates in a plurality of modes including a large document copying mode, a base mode and a chain feeding mode. The chain feeding control circuit comprises a separate counter means for keeping track of a first copy paper being processed while a second copy paper is tracked by a separate counter means. The apparatus and method permits copies to be chain fed in quick succession so that the second document may be exposed immediately after the first document has completed exposure.
